Principles of Light Field Imaging: Briefly revisiting 25 years of research

Ivo Ihrke, John F. Restrepo, Lois Mignard-Debise

Abstract: Light field imaging offers powerful new capabilities through sophisticated digital processing techniques that are tightly merged with unconventional optical designs. This combination of imaging technology and computation necessitates a fundamentally different view of the optical properties of imaging systems and poses new challenges for the traditional signal and image processing domains. In this article, we aim to provide a comprehensive review of the considerations involved and the difficulties encountered in working with light field data.
